Title: Current sensor
Inventor: YAMAGUCHI KATSUMA
IPC: G01R15/20
Filed: 1999-11-15
Abstract: PROBLEM TO BE SOLVED: To make precisely measurable any directional current to be measured in a current sensor operated by the supply of a single power source. SOLUTION: When a current to be measured Iin is made to flow to an input coil 15, a magnetic flux is generate within a magnetic core 10, and a potential difference is caused between a pair of output terminals 14L and 14R provided on a Hall element 12. This potential difference is inputted to a pair of operational amplifiers 20 V and 20 W having a positive voltage Vcc received in the power source terminals. Since both the operational amplifiers 20 V and 20 W have reverse input polarities, only one operational amplifier 20 V takes this voltage potential as a positive input signal and outputs a positive voltage. The operational amplifier 20 V is operated so as to make a current flow to an output coil 21 V and a resistor 22 V so that the potential difference between both the input terminals is 0 V.  The voltage Vout at one end of the resistor 22 to which this current Iout is carried is outputted from a sensor output terminal 23 V as a detection signal.

Title: Pulse generator and discharge lamp lighting device
Inventor: NAKAMURA TOSHIAKI
IPC: H05B41/18
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To provide a pulse generator capable of generating pulses having nearly constant pulse voltage, using a switching element of two-terminal voltage response type. SOLUTION: The primary winding of a pulse transformer PT is connected between the series circuit of voltage sources E1 and E2 and gap elements G1 and G2. A serial circuit between the trigger power source E1 and an impedance element Zt is connected in parallel to the gap element G1. The output voltage of each of voltage sources E1 and E2 is set to be lower than the response voltage of the gap elements G1 and G2, and the sum of the output voltage of both voltage sources E1 and E2 is also set to exceed the response voltage of the gap elements G1 and G2. The output voltage of the trigger power source E1 is controlled so as to exceed the response voltage of the gap element G1 upon the occurrence of pulses.  According to this construction, the sum of the output voltage of the voltage sources E1 and E2 is applied to the gap element G2, due to the continuity of the gap element G1, thereby making the gap element G2 continuous as well.

Title: Personal computer
Inventor: FUJIWARA NAOKI
IPC: G06F1/30
Filed: 1990-11-27
Abstract: PURPOSE:To omit the back-up of a volatile memory and to improve the reliability by using an EEPROM as a memory that backs up the memory contents as well as the system data indispensable to a resuming operation. CONSTITUTION:A BIOS 3 senses the OFF status of a power switch and then checks whether a system is kept in a resuming mode or not. Then the back-up operations are started for the memory contents as well as various system data necessary for application of a resuming function. These back-up data are stored in an EEPROM 6. Then the power down status is transmitted to a power microcomputer and a power supply is actually cut off. When the power switch is turned on again, a flag is checked and an unactuated state is reset when the preceding procedure is reversed. Thus the back-up of the battery is not required for a volatile memory and the life time of the battery can be increased when the resuming function is applied.

Abstract: PROBLEM TO BE SOLVED: To improve safety by providing an obstacle determination means in the lower portion of an upper limb supporting section, the upper portion of a frame or between both, executing downward command prohibition, upward command output at least once, and downward command prohibition cancellation for the frame by detection signals of the obstacle determination means. SOLUTION: A tape switch 20 for determining an obstacle is fixed to the longitudinal direction of the central channel member 17c of the base member of an upper limb supporting section through a fitting device 21. The tape switch 20 is comprised of tape-like upper and lower conductive plates and a backup plate supporting the conductive plates and has a projection provided in the center. If the projection hits an obstacle, and applies a force larger than a prescribed value, the upper and lower conductive plates touch each other and output an obstacle detection signal. Then a control means stops a motor, and stops a downward motion. And then upward movement is executed at least once. If an obstacle ceases to be detected, downward motion prohibition is cancelled. Thus safety can be improved.

Title: Camera for stereo photograph
Inventor: YOSHIZAKI AKIRA
IPC: G03B35/12
Filed: 1988-12-26
Abstract: PURPOSE:To take such a picture that a viewer can watch a proper stereo picture by providing an alarming means which issues the alarm when an angle made by a direction connecting two view points and the horizontal direction of an object exceeds a prescribed angle. CONSTITUTION:An angle detecting encoder 85 and a photoelectric posture detecting sensor 86 detecting the pattern of the angle detecting encoder 85 are arranged on a fan-shaped board 81. In spite of a change in the posture of the camera, an arm 82 points a perpendicular direction owing to the action of a weight 84, and consequently the sensor 86 provided on the side of the camera main body outputs a turning angle signal from the horizontal position of the camera. When the camera turns around an optical axis and a signal outputted from the sensor 86 exceeds a prescribed range, the alarm is issued by lighting an LED in a finder, flickering a display of a stereo mode and sounding a buzzer. Accordingly, a photographer realizes that an appropriate stereo picture cannot be obtained. Thus, such a picture that a viewer can watch a proper stereo picture can be taken.
